The etherington is advertised as a pigoen decoy not a magnet.
I bought one of mick Etherintons pigoen decoyer about 12 months ago and i shoot about 5 days a week. I find it heavey as im on crutches but IKEA dont make them. A lot of friends ive been out with all asked can u get me one. No trouble-- and up to press ive sold about 15 all with a 12 months garentee and no complaints.
